tissues obtained from human volunteers, surgical operations, biopsies, and post-mortem specimens and use them for in vitro studies” (“In Research”). Scientists are able to use human tissue that has been donated from different surgeries and study human biology and diseases. Scientific studies have shown that these alternative tests are not only more accurate, but more humane for animals. “Alternative scientific tests are often more reliable than animal tests” (“In Testing”).…

A highly controversial, and relatively new, argument of utilizing animals in the testing and development of medical research has left scientists in the crossroads on the ethics behind the entire operation. Approximately twenty-six million animals are in the United Stated each year for both scientific and commercial testing, in which these animals are used for a wide range of dangerous procedures. These animals are used for testing the safety of medications for human consumption, determining the…

YR 10 Science Evolutionary Theory Alicia Horsfield Evolution can be defined as a gradual process in which a species changes into a different and more complex form. This happens over several generations. Evolution also proves that all species are related through genetic variation. (yourgenome.org, n.e). Charles Darwin (1809-1882) was an English Naturalist, famous for creating the theory of ‘evolution’. He also created a theory that species survive through a process called “natural selection”.…

Evolution When talking about evolution, people generally think of Charles Darwin as the originator or “father” of evolution. Even though Darwin may have opened the door for evolution and proved his hypothesis to be correct through his experiments, he had been influenced by many scientists before him. Although Darwin’s theory of natural selection is considered legitimate, there are many other theories to be equitable as well, much like the inheritance of acquired characteristics. Charles Darwin’s…

Using Integrating Concepts in Biology (ICB)”, an introductory resource for this year’s electronic textbook, and answer the following discussion questions. Responses should be uploaded to Canvas by 11:59PM on 9/20/15. A PDF version of this guide is posted to Canvas, and can also be found in the e-text. 1. The ICB text is organized around five “big ideas” in biology. List them, then define the term that is bolded in the text of each one. The five big ideas in biology are 1: living systems…

This period emphasized the self, creativity, imagination and the value of art. It was a movement that strongly emphasized emotion. It also legitimized ‘individual imagination' as a major authority. Which in turn gave rise to ‘free expression' in art. With such an emphasis on feelings and imagination many thinkers of this period introduced philosophies and theologies of their own on this topic. Richard Kearney in The Wake of the Imagination, explores the various concepts of imagining from the…

“I have no objection to cloning as such as a technological instrument for medical and therapeutic purposes. As in all these cases, what must govern one 's decisions is the question of compassionate motivation. However, regarding the idea of deliberately breeding semi-human beings for spare parts, I feel an immediate, instinctive revulsion,” -Dalai Lama. Cloning should be regulated by a moral compass to prevent unethical procedures and practices with this technology. The moral compass should be a…

The Best Time to Learn and Succeed The easiest and cheapest time for one to learn is at the early stage of life, when one is still in the prime to be able catch and release any information as needed by any environment one may be in at the time. Learning new things are the simplest ways the brain of a person develops from infant to child, to a teenager, and to adult, through the use of new information, processing of the information created or gathered, and maturing to use all the information…

When we think of analogous and homologous traits, we have to draw I close distinction between them. That is the main reason it is essential to mention that homology refers to similar traits that an organism share with another. Homologous traits are a product of direct inheritance (in other words, they are acquired as a result of one common ancestor). On the other hand, analogous refers to the trait that- although originally developed to serve a different function- have evolved to carry out an…

New Reproductive technologies have opened a world of possibilities for having children, creating families, and creating bonds that are deeper than genetics. In particular, surrogacy is the most efficient and effective reproductive technology when trying to accomplish this. In this paper, I will argue that surrogacy redefines the definition of family in a positive light. Surrogacy is changing the world we live in for the better by creating bonds between human beings based on relationships,…
